New Rochelle Premium Roofing provides professional chimney flashing in New Rochelle, NY for residential and commercial properties across Westchester County. A chimney re-flash on a shingle roof is an afternoon. On a slate roof it is a different job entirely, because every slate around the stack has to come off with a ripper and go back on a hook, and that access drives the price.
Which is why we schedule chimney metal against the covering rather than after it. If the slate on that slope is being relaid within the next few years, the flashing gets done in the same lift and the labor is shared between the two scopes. If it is not, the chimney work stands alone and costs several times what the same detail costs on asphalt, and you should know that before you choose.
The metal itself is straightforward when it is done right. Apron at the front, individual step flashings woven one per course up both sides, a soldered pan behind, a framed and metal-lined cricket on any stack over roughly thirty inches wide, and counterflashing seated into a mortar joint raked out above. Lead-coated copper is our default because it weathers to a soft gray and will not stain limestone or light brick.
What fails is almost never the brick itself. It is a single piece of aluminum bent over the stack and bedded in sealant, or step flashing that was reused from the last roof because pulling new metal took time, or a cricket that was never built because the roofer did not want to frame one. Those three details account for the large majority of chimney calls we take.
We do not seal our way out of it. Roof cement smeared into the joint between metal and masonry is a one-winter repair that leaves a mess for whoever comes next, and it conceals the actual failure rather than correcting it. Old cement gets scraped and cleaned off entirely, and the detail gets rebuilt in properly formed and soldered metal. Cement hides the failure and adds a day of labor for the next roofer.
Masonry work is coordinated rather than improvised. Crowns, repointing and rebuilds are done by a mason before any metal goes back on, and the disposition of an unused flue is settled in writing when a live gas or oil appliance is vented anywhere in the stack. A live flue changes what may be capped, and that is settled before any metal is fabricated.
Our licensed and insured team brings the right materials and equipment to every job — lead-coated copper step and pan flashing, twenty-ounce cold-rolled copper valley linings, slate rippers and copper bib repairs, stainless slate hooks set at the head lap, semi-weathering gray and unfading green roofing slate, terne-coated stainless bay-roof pans — and backs the work with a written workmanship warranty. We serve New Rochelle and nearby communities including Larchmont, Mamaroneck, Pelham, Pelham Manor.

Materials, equipment and how we do chimney flashing
The difference between chimney flashing that lasts and chimney flashing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with lead-coated copper step and pan flashing, twenty-ounce cold-rolled copper valley linings, slate rippers and copper bib repairs, stainless slate hooks set at the head lap, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every New Rochelle job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in Westchester County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
